Patent number: 5230708Abstract: This invention relates to improved methods and compositions to enhance stain resistance of carpet fiber. The improved methods relate to a continuous aftertreatment for dyed carpet fabric and to two-step processes, either batch-batch, batch-continuous or continuous-continuous. The improved compositions are used in the processes to enhance stain resistance of carpet or carpet fiber and to overcome various prior drawbacks, such as, yellowing, oxidation and durability to cleaning. The sulfonated aromatic condensates are used to enhance stain resistance, and can be combined with fluorocarbon compounds for soil resistance, thiocyanates, and/or salts having divalent cations, such as magnesium sulfate. Also various dispersing agents, buffering acids and sequestering agents are disclosed.Type: GrantFiled: June 1, 1989Date of Patent: July 27, 1993Assignee: Allied-Signal Inc.Inventors: Dale A. Hangey, Paul W. Harris, Daniel J. Corcoran, Jr., Michael P. Friedberger, Charles J. Cole, William A. Archie, Roger N. Spitz

Patent number: 5135774Abstract: A method to impart coffee stain resistance to polyamide fibers such as those found in textile substrates (e.g., carpets). The method includes preparing an aqueous dispersion of charged microfine beads of either (i) a copolymer selected from the group consisting of a hydrolyzed aromatic-containing vinyl ether maleic anhydride copolymer, a half ester of an aromatic-containing vinyl ether maleic anhydride copolymer, and mixtures thereof, or (ii) an aromatic-containing acrylate copolymerized with an acid selected from the group consisting of acrylic acid and maleic acid, immersing the polyamide fiber in the aqueous dispersion so that the beads contact and coat the fiber via an electrostatic attraction. The aqueous dispersion is prepared by dissolving the polymer into a water-soluble solvent to form a solution, injecting the solution into water, and evaporating the solvent.Type: GrantFiled: March 27, 1990Date of Patent: August 4, 1992Assignee: Allied-Signal Inc.Inventors: Lidia T.

Patent number: 5131909Abstract: In a continuous application process with post-steaming, SAC's having molecular size (hydrodynamic volume) defined by elution volume (Ve) determined by Size Exclusion Chromatography (SEC) of between 6.3 and 6.5 ml. using the procedure described, are such that they are not too small so that migration into the fiber occurs (reduces ring dyeing effect) nor are they too large such that they require extremely long steaming times or the use of swelling agents to be effective. This is independent of the degree of sulfonation of the SAC.Type: GrantFiled: May 17, 1990Date of Patent: July 21, 1992Assignee: Allied-Signal Inc.Inventor: Dale A. Hangey
